Yes ... No

Several times a week, in fact almost every day, I find myself driving with both girls in the backseat. Now that they are both vocal, I get the distinct pleasure of overhearing the deep, meaningful discussions between a two year old and a four year old. Today's conversation quickly became an argument:

Catherine (the four year old): Sabrina, you are my sister.

Sabrina (the two year old): No, I'm not.

Catherine: Yes you are.

Sabrina: No.

Catherine: Yes.

Sabrina: No.

Catherine: Yes.

Sabrina: No.

Catherine (yelling at this point): MOMMY! Sabrina says she's not my sister!! Tell her she is!!

Sabrina: No!
